下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与发明相关的部分。The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the related invention, but not to limit the invention. In addition, it should be noted that, for the convenience of description, only the parts related to the invention are shown in the drawings.
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
在现有的配置有账户模型的区块链中，都是基于虚拟机和合约实现业务逻辑。为了保证安全，一个合约不能调用另一合约的资产。如果A合约可以调用B合约中的资产，则A合约就是超级管理员，会破坏B合约的业务逻辑：例如，B合约是交易合约，有一笔交易，该交易为某用户冻结了100MM，如果另一用户给他10NN，他就给对方100MM。此时，如果A合约直接把B合约中的100MM给解冻并找回，就会引起给了10NN的用户无法收到100MM。In the existing blockchains configured with an account model, business logic is implemented based on virtual machines and contracts. For security, one contract cannot call another contract's assets. If contract A can call assets in contract B, then contract A is a super administrator, which will destroy the business logic of contract B: for example, contract B is a transaction contract, and there is a transaction that freezes 100MM for a user. Once the user gives him 10NN, he will give the other party 100MM. At this time, if contract A directly unfreezes and retrieves the 100MM in contract B, it will cause users who have given 10NN to not receive 100MM.
因此在现有技术中，要实现钱包找回功能，首先需要将若干资产转至钱包找回合约，即，只有钱包找回合约中的资产是可以被找回的。Therefore, in the prior art, in order to realize the wallet retrieval function, it is necessary to first transfer several assets to the wallet retrieval contract, that is, only the assets in the wallet retrieval contract can be retrieved.
图1为本发明一实施例提供的一种钱包找回方法的流程图。如图1所示，在本实施例中，适用于客户端的钱包找回方法，区块链配置有账户模型，上述方法包括：FIG. 1 is a flowchart of a method for retrieving a wallet according to an embodiment of the present invention. As shown in FIG. 1, in this embodiment, the wallet retrieval method applicable to the client is configured with an account model on the blockchain, and the above method includes:
S12：响应于将第二公钥的第二账户中的若干资产找回到第一公钥的第一账户中，生成第一钱包找回交易；其中，第一钱包找回交易的签名信息中包括钱包找回标识、延时信息、第一公钥、第二公钥；S12: In response to retrieving several assets in the second account of the second public key back into the first account of the first public key, generate a first wallet retrieval transaction; wherein the signature information of the first wallet retrieval transaction is Including wallet retrieval ID, delay information, first public key, second public key;
S14：将第一钱包找回交易发送至区块链网络，以供区块链节点：S14: Send the first wallet retrieval transaction to the blockchain network for the blockchain node:
缓存第一钱包找回交易，并根据延时信息确定起始打包时刻；Cache the first wallet to retrieve the transaction, and determine the starting packaging time according to the delay information;
在到达起始打包时刻，且拥有起始打包时刻后的最新的第一区块的打包权时，执行第一钱包找回交易：将若干资产从第二账户划 转至第一账户；以及，When the initial packaging time is reached and the packaging right of the latest first block after the initial packaging time is reached, the first wallet retrieval transaction is executed: several assets are transferred from the second account to the first account; and,
将包括第一钱包找回交易的第一区块广播至其它区块链节点，以供其它区块链节点删除本地的第一钱包找回交易。Broadcast the first block including the first wallet retrieval transaction to other blockchain nodes, so that other blockchain nodes can delete the local first wallet retrieval transaction.
具体地，以将打算挖矿的挖矿合约资产1000MM从addr(A)找回到addr(B)为例；假设延时信息为2021年1月1日0:00:00；Specifically, take the example of retrieving 1000MM of mining contract assets to be mined from addr(A) to addr(B); assuming that the delay information is 0:00:00 on January 1, 2021;
响应于将打算挖矿的挖矿合约资产1000MM从addr(A)找回到addr(B)，客户端执行步骤S12，生成钱包找回交易tx1，tx1的签名信息中包括{uwallet:公钥(A):公钥(B):2021年1月1日0:00:00:sigdata1}；其中，uwallet是钱包找回标识，2021年1月1日0:00:00是延时信息，addr(B)是公钥(B)的账户，addr(A)是公钥(A)的账户，sigdata1为交易发起方根据所持有的私钥对tx1的交易内容进行签名后获得的签名数据；In response to retrieving 1000MM of mining contract assets to be mined from addr(A) to addr(B), the client performs step S12 to generate a wallet retrieval transaction tx1, where the signature information of tx1 includes {uwallet:public key( A): Public key (B): January 1, 2021 0:00:00: sigdata1}; among them, uwallet is the wallet retrieval ID, January 1, 2021 0:00:00 is the delay information, addr (B) is the account of the public key (B), addr(A) is the account of the public key (A), and sigdata1 is the signature data obtained after the transaction initiator signs the transaction content of tx1 according to the private key held;
客户端执行步骤S14，将tx1发送至区块链网络；The client performs step S14, and sends tx1 to the blockchain network;
区块链节点缓存tx1，并确定tx1的起始打包时刻，起始打包时刻为2021年1月1日0:00:00；The blockchain node caches tx1 and determines the starting packaging time of tx1, which is 0:00:00 on January 1, 2021;
假设区块链节点A在达到2021年1月1日0:00:00，且拥有2021年1月1日0:00:00后的最新区块block(100)的打包权，则节点A执行tx1：将挖矿合约资产1000MM从addr(A)划转至addr(B)；Assuming that blockchain node A reaches 0:00:00 on January 1, 2021, and has the packaging right of the latest block (100) after 0:00:00 on January 1, 2021, node A executes tx1: Transfer 1000MM of mining contract assets from addr(A) to addr(B);
区块链节点A将包括tx1的block(100)至其它区块链节点，其它区块链节点在收到block(100)后，删除本地的tx1。Blockchain node A will include block(100) of tx1 to other blockchain nodes, and other blockchain nodes will delete the local tx1 after receiving block(100).
在更多实施例中，延时信息还可以根据实际需求配置为第二时长，相应的，起始打包时刻应当根据额外设定的时间起始点、第二时长确定，例如将“缓存第一钱包找回交易，并根据延时信息确定起始打包时刻”配置为“缓存第一钱包找回交易，并根据第一钱包找回交易的生成时刻、第二时长确定起始打包时刻”，可实现相同的技术效果。In more embodiments, the delay information can also be configured as a second duration according to actual requirements. Correspondingly, the start packing time should be determined according to the additionally set time starting point and second duration. For example, "cache the first wallet" Retrieve the transaction, and determine the starting packaging time according to the delay information" is configured as "cache the first wallet retrieval transaction, and determine the starting packaging time according to the generation time and the second duration of the first wallet retrieval transaction", which can be achieved The same technical effect.
本领域技术人员应当理解，1000MM属于挖矿合约，是因为tx1指定了挖矿合约执行器，若tx1未指定合约，则是将全局资产1000MM从addr(A)划转至addr(B)。Those skilled in the art should understand that 1000MM is a mining contract because tx1 specifies a mining contract executor. If tx1 does not specify a contract, the global asset 1000MM is transferred from addr(A) to addr(B).
本领域技术人员应当理解，公钥(A)和公钥(B)可以属于同一个用户，也可以属于不同用户。Those skilled in the art should understand that the public key (A) and the public key (B) may belong to the same user, or may belong to different users.
本领域技术人员应当理解“，将若干资产从第二账户划转至第一账户”中的若干资产应当为活动的资产，若上述若干资产为冻结状态，则先解冻上述若干资产，再将解冻的若干资产从第二账户划转至第一账户。Those skilled in the art should understand that several assets in "transferring several assets from the second account to the first account" should be active assets. If the above-mentioned several assets are in a frozen state, the above-mentioned several assets shall be unfrozen first, and then the above-mentioned several assets shall be unfrozen. A number of assets are transferred from the second account to the first account.
上述实施例使得任意资产都可以被找回。The above-described embodiments allow any asset to be retrieved.
优选地，签名信息中还包括可以对第二公钥进行管理的各第三账户的第三公钥、可以成功执行第一钱包找回交易的钱包找回判断规则、若干第四账户根据所持有的私钥对第一钱包找回交易的交易内容进行签名获得的第一签名数据；Preferably, the signature information also includes third public keys of each third account that can manage the second public key, wallet retrieval judgment rules that can successfully execute the first wallet retrieval transaction, and several fourth accounts according to the Some private keys are the first signature data obtained by signing the transaction content of the first wallet retrieval transaction;
执行第一钱包找回交易包括：Executing the first wallet retrieval transaction includes:
判断签名信息中的各第一签名数据是否符合钱包找回判断规则：Determine whether each first signature data in the signature information conforms to the wallet retrieval judgment rule:
是，则执行第一钱包找回交易。If yes, execute the first wallet retrieval transaction.
具体地，以钱包找回判断规则包括至少应当收到的第一签名数据的第一数量，及，正确签名的第一签名数据的第二数量；判断签名信息中的各第一签名数据是否符合钱包找回判断规则包括“判断签名信息中第一签名数据的数量是否不少于第一数量：是，则判断签名信息中签名正确的第一签名数据的数量是否不少于第二数量”为例；假设可以对公钥(A)进行管理的账户的公钥有公钥(N1)～公钥(N4)；tx1的签名信息中包括{uwallet:addr(A):addr(B):3:2:2021年1月1日0:00:00:sigdata1:sigdata2:sigdata3}；其中，3:2为找回判断规则，3表示最少需要获得3个签名数据，该3个签名数据对应的公钥应当包括于公钥(N1)～公钥(N4)，2表示3个签名数据中至少有2个签名数据是正确的；sigdata1:sigdata2:sigdata3为签名数据，且在当前实施例中，假设sigdata1:sigdata2:sigdata3均为正确的签名数据，且对应的公钥均包括于公钥(N1)～公钥(N4)；Specifically, the wallet retrieval judgment rule includes at least the first quantity of first signature data that should be received, and the second quantity of correctly signed first signature data; it is judged whether each first signature data in the signature information conforms to The wallet retrieval judgment rules include "judging whether the number of the first signature data in the signature information is not less than the first number: yes, then determine whether the number of the first signature data with correct signatures in the signature information is not less than the second number" as follows: For example; it is assumed that the public key of the account that can manage the public key (A) includes the public key (N1) ~ the public key (N4); the signature information of tx1 includes {uwallet:addr(A):addr(B):3 :2:January 1, 2021 0:00:00:sigdata1:sigdata2:sigdata3}; among them, 3:2 is the retrieval judgment rule, 3 means that at least 3 signature data need to be obtained, the corresponding 3 signature data The public key should be included in the public key (N1) to the public key (N4), and 2 indicates that at least two of the three signature data are correct; sigdata1:sigdata2:sigdata3 are signature data, and in the current embodiment, Assume that sigdata1:sigdata2:sigdata3 are all correct signature data, and the corresponding public keys are included in public key (N1) ~ public key (N4);
由于sigdata1:sigdata2:sigdata3均为正确的签名数据，且对应的公钥均包括于公钥(N1)～公钥(N4)，符合tx1中的钱包找回判断规则“3:2”，节点A执行tx1：将挖矿合约资产1000MM从addr(A)划转至addr(B)。Since sigdata1:sigdata2:sigdata3 are all correct signature data, and the corresponding public key is included in the public key (N1) ~ public key (N4), it conforms to the wallet retrieval judgment rule "3:2" in tx1, node A Execute tx1: Transfer 1000MM of mining contract assets from addr(A) to addr(B).
在更多实施例中，钱包找回判断规则还可以根据实际需求进行配 置，例如配置为，3:50％，其中3表示最少需要获得从3个签名数据，50％表示3个签名数据中至少有2个签名(1.5的向上取整)数据是正确的，可实现相同的技术效果。且本领域技术人员应当理解，多重签名规则不仅可以根据数量进行配置，还可以根据实际需求根据权重或其它参数进行配置，可实现相同的技术效果。In more embodiments, the wallet retrieval judgment rule can also be configured according to actual needs, for example, it is configured as 3:50%, where 3 means that at least three signature data need to be obtained, and 50% means that at least 3 signature data need to be obtained. Having 2 signatures (round up of 1.5) data is correct and achieves the same technical effect. It should be understood by those skilled in the art that the multi-signature rule can be configured not only according to the quantity, but also according to the weight or other parameters according to the actual requirements, so as to achieve the same technical effect.
进一步的，判断签名信息中的各第一签名数据是否符合钱包找回判断规则包括：Further, judging whether each first signature data in the signature information conforms to the wallet retrieval judgment rule includes:
判断各第四账户是否均属于第三账户：Determine whether each fourth account belongs to the third account:
是，则判断签名信息中第一签名数据的数量是否不少于第一数量。If yes, then judge whether the quantity of the first signature data in the signature information is not less than the first quantity.
在一些区块链***中，钱包找回交易中的签名数据对应的公钥应当均属于第三账户，在另一些区块链***中，钱包找回交易的签名数据对应的公钥可以不全属于第三账户，只要对应的公钥属于第三账户的数量或权重或其它参数符合钱包找回判断规则即可。In some blockchain systems, the public keys corresponding to the signature data in the wallet retrieval transaction should all belong to the third account. In other blockchain systems, the public keys corresponding to the signature data in the wallet retrieval transaction may not all belong to the third account. For the third account, as long as the corresponding public key belongs to the number or weight of the third account or other parameters meet the wallet retrieval judgment rules.
本领域技术人员应当理解，在收到第一钱包找回交易时，应当先判断该第一钱包找回交易是否同时为多重签名交易，即该钱包找回交易的签名信息中不应该缺少以下任意参数“对第二公钥进行管理的各第三账户的第三公钥、可以成功执行第一钱包找回交易的钱包找回判断规则、若干第四账户根据所持有的私钥对第一钱包找回交易的交易内容进行签名获得的第一签名数据”；若缺少上述任意参数，则根据实际需求处理该钱包找回交易，例如，不执行该钱包找回交易。Those skilled in the art should understand that when receiving a first wallet retrieval transaction, it should first determine whether the first wallet retrieval transaction is a multi-signature transaction at the same time, that is, the signature information of the wallet retrieval transaction should not lack any of the following Parameter "The third public key of each third account that manages the second public key, the wallet recovery judgment rule that can successfully execute the first wallet recovery transaction, and several fourth accounts based on the private key held by the first wallet. The first signature data obtained by signing the transaction content of the wallet retrieval transaction"; if any of the above parameters are missing, the wallet retrieval transaction will be processed according to actual needs, for example, the wallet retrieval transaction will not be executed.
本领域技术人员应当理解，区块链支持多种签名类型。It should be understood by those skilled in the art that a blockchain supports a variety of signature types.
在现有技术中，当前区块链仅支持一些例如secp的基础签名类型，在本申请中，区块链可以根据实际需求支持更多种类的签名类型。不同的签名类型的密钥空间不同，例如secp的密钥空间是0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140，而bls的密钥空间是0x73eda753299d7d483339d80809a1d80553bda402fffe5bfeffffffff00000001，则区块链节点在验证钱包找回交易的各签名数据时，还需要根据签名数据指定的签名类型进行验证。In the prior art, the current blockchain only supports some basic signature types such as secp. In this application, the blockchain can support more types of signatures according to actual needs.不同的签名类型的密钥空间不同，例如secp的密钥空间是0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140，而bls的密钥空间是0x73eda753299d7d483339d80809a1d80553bda402fffe5bfeffffffff00000001，则区块链节点在验证When the wallet retrieves each signature data of the transaction, it also needs to be verified according to the signature type specified by the signature data.
进一步的，钱包找回判断规则包括至少应当收到的第一签名数据 的第一数量，及，正确签名的第一签名数据的第二数量；Further, the wallet retrieval judgment rule includes at least the first quantity of the first signature data that should be received, and the second quantity of the correctly signed first signature data;
判断签名信息中的各第一签名数据是否符合钱包找回判断规则包括：Judging whether each first signature data in the signature information conforms to the wallet retrieval judgment rules includes:
判断签名信息中第一签名数据的数量是否不少于第一数量：Determine whether the quantity of the first signature data in the signature information is not less than the first quantity:
是，则判断签名信息中签名正确的第一签名数据的数量是否不少于第二数量。If yes, then determine whether the number of correctly signed first signature data in the signature information is not less than the second number.
上述实施例的钱包找回原理可参考图1所示的一种优选实施方式的方法，此处不再赘述。For the wallet retrieval principle in the above embodiment, reference may be made to the method of a preferred embodiment shown in FIG. 1 , and details are not repeated here.

缓存第一钱包找回交易，并根据延时信息确定起始打包时刻。The first wallet is cached to retrieve the transaction, and the starting packaging time is determined according to the delay information.
具体地，tx1包括于钱包找回存证交易tx2的payload中；Specifically, tx1 is included in the payload of the wallet retrieval deposit certificate transaction tx2;
区块链节点扣除tx2的手续费，将tx2存证在区块链上；The blockchain node deducts the handling fee of tx2 and stores the tx2 certificate on the blockchain;
区块链节点将tx2的payload中的tx1缓存，并根据tx1的延时信息确定tx1的起始打包时刻。The blockchain node caches tx1 in the payload of tx2, and determines the starting packaging time of tx1 according to the delay information of tx1.
在上述实施例中，区块链节点不免费为有延时信息的多重签名交易提供存储服务，而是需要收取一定的手续费，上述实施例可以避免客户端发送大量有延时信息的多重签名，大量占用区块链节点本地的存储空间，从而增强了区块链网络的安全性。In the above embodiment, the blockchain node does not provide storage services for multi-signature transactions with delayed information for free, but needs to charge a certain handling fee. The above embodiment can prevent the client from sending a large number of multi-signatures with delayed information. , which occupies a large amount of local storage space of the blockchain node, thereby enhancing the security of the blockchain network.
进一步的，延时信息为钱包找回交易所需延长的第一时长；缓存第一钱包找回交易，并根据延时信息确定起始打包时刻包括：Further, the delay information is the first time duration required for the wallet to retrieve the transaction; cache the first wallet to retrieve the transaction, and determine the start packing time according to the delay information, including:

将第一钱包找回交易存储到本地，并存储第一钱包找回存证交易的第一哈希值与第一钱包找回交易的第二哈希值的第一对应关系；Store the first wallet retrieval transaction locally, and store the first correspondence between the first hash value of the first wallet retrieval transaction and the second hash value of the first wallet retrieval transaction;
其中，第一对应关系用于供其它区块链节点：Among them, the first correspondence is used for other blockchain nodes:
在执行第一钱包找回交易时，根据第二哈希值找到第一钱包找回存证交易，并根据第一钱包找回存证交易被打包的第一时刻、第一时长确定第一钱包找回交易的起始打包时刻；When executing the first wallet retrieval transaction, the first wallet retrieval certificate transaction is found according to the second hash value, and the first wallet is determined according to the first moment and the first duration when the first wallet retrieval certificate transaction is packaged Retrieve the starting packaging moment of the transaction;
判断第一钱包找回交易的打包时刻是否不早于起始打包时刻：Determine whether the packaging time of the first wallet retrieval transaction is not earlier than the initial packaging time:
否，则第一钱包找回交易执行不成功。If not, the first wallet retrieval transaction is unsuccessful.
具体地，假设tx2被打包的第一时刻为2020年11月24日0:00:00，第一时长为7天，A生成的区块的生成时间为2020年12月30日0:00:00；Specifically, it is assumed that the first moment when tx2 is packaged is 0:00:00 on November 24, 2020, the first duration is 7 days, and the generation time of the block generated by A is 0:00 on December 30, 2020: 00;
区块链节点根据tx2被打包的时刻2020年11月24日0:00:00、7天确定tx1的起始打包时刻，tx1的起始打包时刻为2021年1月1日0:00:00；The blockchain node determines the starting packaging time of tx1 according to the time when tx2 was packaged at 0:00:00 on November 24, 2020 and 7 days, and the starting packaging time of tx1 is at 0:00:00 on January 1, 2021 ;
区块链节点将tx1存储到本地，并存储hash(tx2)和hash(tx1)的对应关系；The blockchain node stores tx1 locally, and stores the correspondence between hash(tx2) and hash(tx1);
其它区块链节点在收到A生成的区块，在执行到tx1时，根据hash(tx1)找到tx2，并根据tx1被打包的时刻2020年11月24日0:00:00、第一时长7天确定tx1的起始打包时刻，tx1的起始打包时刻为2021年1月1日0:00:00；When other blockchain nodes receive the block generated by A, when tx1 is executed, they will find tx2 according to hash(tx1), and according to the time when tx1 was packaged at 0:00:00 on November 24, 2020, the first duration 7 days to determine the starting packing time of tx1, the starting packing time of tx1 is 0:00:00 on January 1, 2021;
其它区块链节点判断2020年12月30日0:00:00是否不早于起始打包时刻2021年1月1日0:00:00；Other blockchain nodes judge whether 0:00:00 on December 30, 2020 is not earlier than the start packaging time at 0:00:00 on January 1, 2021;
由于2020年12月30日0:00:00早于起始打包时刻2021年1月1日0:00:00，其它区块链节点执行tx1失败。Since 0:00:00 on December 30, 2020 is earlier than the start packaging time at 0:00:00 on January 1, 2021, other blockchain nodes fail to execute tx1.
由于大多数节点执行tx1失败，将导致区块链节点A生成的错误区块成为侧链上的区块，最终使得addr(A)的资产的安全性得到保障。Since most nodes fail to execute tx1, the erroneous block generated by blockchain node A will become the block on the side chain, and finally the security of addr(A) assets will be guaranteed.
